preparation example Construction

[0080] The preparation method of esomeprazole magnesium enteric-coated pellets is as follows:

[0081] ⑴Isolation gown layer

[0082] Purpose: To isolate the sugar pill from the active ingredient layer, so that the surface of the sugar pill is smoother and rounder.

[0083] prescription:

[0084]

[0085] Preparation process: ① Weigh purified water and pour it into a container, add the above three auxiliary materials while stirring, and stir for 10-20 minutes to obtain a solution for later use.

[0086] ② Pour the medicinal pellet core into the bottom spray coating pot, set the inlet air temperature: 40-65°C, air volume:

[0087] 200-1500m 3 / h, control the liquid supply speed:

[0088] Spray liquid at 8-50rpm, dry, and increase the weight of the coating by 5%-12%.

[0089] ⑵ drug layer

[0090] Purpose: To coat the active ingredient layer.

[0091] prescription:

Abstract

The invention provides capsules prepared from enteric-pellets containing esomeprazole magnesium. The enteric-pellets containing the esomeprazole magnesium at least comprise hollow sugar pill cores (A), isolation coating layers (B), esomeprazole magnesium medicine layers (C) and alkaline isolation coating layers (D). By coating the esomeprazole magnesium medicine layers with the alkaline isolation coating layers, the enteric-pellets have improved stability, and then the capsules have improved stability.

Description

technical field [0001] The present invention relates to storage stable esomeprazole magnesium enteric-coated pellet capsules prepared from enteric-coated pellets containing esomeprazole magnesium and a preparation method thereof, more specifically, relates to esomeprazole magnesium from esomeprazole magnesium Esomeprazole magnesium enteric-coated micropill capsules prepared from enteric-coated pellets containing esomeprazole magnesium which are stable in storage and coated with an alkaline isolation coating layer outside the azole magnesium drug layer and its preparation method . Background technique [0002] Esomeprazole magnesium for gastroesophageal reflux disease: treatment of erosive reflux esophagitis, long-term maintenance treatment to prevent recurrence of cured esophagitis patients, symptom control of gastroesophageal reflux disease; also used It is used in combination with appropriate antimicrobial therapy to eradicate Helicobacter pylori and heal duodenal ulcers ...
